Were I you, I would contact the local police and see if they can direct you to whoever licenses PIs. Once you've located the licensing board, you can get all the info you need from them. And it may be that the police license PIs. If not them, it's likely one or the city department. Requirements vary from state to state, so without talking to a PI, it's a bit hard to know what the particular requirements are in your area.

Its vary by state. Collect information about criteria in your state, for example In California it takes 6,000 hours, or about 3 years fulltime work, under a licensed investigator to be eligible to take the state-issued exam.
